Evaluation of an inflammation-based prognostic score in patients with inoperable pancreatic cancer

Investigation of the association between therapeutic effectiveness of anamorelin and Glasgow prognostic score in patients with cancer cachexia: a competing risk analysis

Anamorelin, a highly selective ghrelin receptor agonist, enhances appetite and increases lean body mass in patients with cancer cachexia. However, the predictors of its therapeutic effectiveness are uncertain. This study aimed to investigate the association between the Glasgow prognostic score (GPS), used for classifying the severity of cancer cachexia, the therapeutic effectiveness of anamorelin, and the feasibility of early treatment based on cancer types. A retrospective analysis included patients with gastric, pancreatic, colorectal, and non-small-cell lung cancer treated with anamorelin between May 2021 and July 2022. The endpoints were the response rate for increased appetite within 3 weeks of treatment initiation and the time to treatment failure (TTF) due to therapeutic failure of anamorelin. Multivariate logistic regression model and Fine and Gray's model were used for analysis. Of the 137 patients in this analysis, 51% of patients had a GPS of 0 or 1, and 49% of those had a GPS of 2. Patients with a GPS of 2 showed a lower response for increased appetite than those with a GPS of 0 or 1 (adjusted odds ratio 0.29 [95% CI 0.12-0.72], P = 0.007). Additionally, TTF was shorter in patients with a GPS of 2 with a GPS of 0 or 1 (adjusted subdistribution hazard ratio 2.22 [95% CI 1.22-4.03], P = 0.009). Anamorelin could be more effective in improving appetite and prolonging the duration of treatment effect in patients with a GPS of 0 or 1 than those with a GPS of 2.

The prognostic impact of C-reactive protein and albumin in patients diagnosed with acute myeloid leukaemia

Background

Acute myeloid leukaemia (AML) is an aggressive and heterogeneous malignant disease. Patient age, comorbidities and disease-specific genetic abnormalities are recognized as primary determinants of treatment response. Recent years have elucidated the significance of nutritional status and inflammation across various malignancies, including AML, in influencing treatment outcomes.

Aims

To assess the prognostic value of the C-reactive protein-albumin ratio (CAR) and the Glasgow Prognostic Score (GPS) in predicting overall survival (OS) rates among patients diagnosed with AML.

Material and methods

189 AML patients receiving standard cytarabine and anthracycline-based induction treatment were included. Baseline demographic, clinical and laboratory data were collected, and treatment outcomes and survival were registered for all patients.

Results

No significant association between CAR and prognosis among AML patients was found, even in subgroup analyses. Hypoalbuminemia was an independent predictor of poor survival among all patients (OS 28 vs. 16 months; p < 0.02). Patients with a GPS of 0 or 1 demonstrated superior OS compared to those with a GPS of 2 (median OS 28 vs. 16 months, respectively; p = 0.015). Results remained consistent among patients ≥ 60 years (median OS 15 vs. 6 months; p = 0.020).

Conclusion

Heightened inflammation and suboptimal nutritional status correlate with unfavourable prognoses in AML patients. Such insights hold the potential for guiding clinical decision-making, offering easily accessible prognostic information for the induction treatment of eligible AML patients.

Re-assessing the role of peri-operative nutritional therapy in patients with pancreatic cancer undergoing surgery: a narrative review

Pancreatic cancer is the most common medical condition that requires pancreatic resection. Over the last three decades, significant improvements have been made in the conditions and procedures related to pancreatic surgery, resulting in mortality rates lower than 5%. However, it is important to note that the morbidity in pancreatic surgery remains r latively high, with a percentage range of 30-60%. Pre-operative malnutrition is considered to be an independent risk factor for post-operative complications in pancreatic surgery, such as impaired wound healing, higher infection rates, prolonged hospital stay, hospital readmission, poor prognosis, and increased morbidity and mortality. Regarding the post-operative period, it is crucial to provide the best possible management of gastrointestinal dysfunction and to handle the consequences of alterations in food digestion and nutrient absorption for those undergoing pancreatic surgery. The European Society for Clinical Nutrition and Metabolism (ESPEN) suggests that early oral feeding should be the preferred way to initiate nourishing surgical patients as it is associated with lower rates of complications. However, there is ongoing debate about the optimal post-operative feeding approach. Several studies have shown that enteral nutrition is associated with a shorter time to recovery, superior clinical outcomes and biomarkers. On the other hand, recent data suggest that nutritional goals are better achieved with parenteral feeding, either exclusively or as a supplement. The current review highlights recommendations from existing evidence, including nutritional screening and assessment and pre/post-operative nutrition support fundamentals to improve patient outcomes. Key areas for improvement and opportunities to enhance guideline implementation are also highlighted.

Evaluation of the inflammation-based modified Glasgow Prognostic Score (mGPS) as a prognostic and predictive biomarker in patients with metastatic colorectal cancer receiving first-line chemotherapy: a post hoc analysis of the randomized phase III XELAVIRI trial (AIO KRK0110)

BACKGROUND

The inflammation-based modified Glasgow Prognostic Score (mGPS) combines serum levels of C-reactive protein and albumin and was shown to predict survival in advanced cancer. We aimed to elucidate the prognostic impact of mGPS on survival as well as its predictive value when combined with gender in unselected metastatic colorectal cancer (mCRC) patients receiving first-line chemotherapy in the randomized phase III XELAVIRI trial.

PATIENTS AND METHODS

In XELAVIRI, mCRC patients were treated with either fluoropyrimidine/bevacizumab followed by additional irinotecan at first progression (sequential treatment arm; Arm A) or upfront combination of fluoropyrimidine/bevacizumab/irinotecan (intensive treatment arm; Arm B). In the present post hoc analysis, survival was evaluated with respect to the assorted mGPS categories 0, 1 or 2. Interaction between mGPS and gender was analyzed.

RESULTS

Out of 421 mCRC patients treated in XELAVIRI, 362 [119 women (32.9%) and 243 men (67.1%)] were assessable. For the entire study population a significant association between mGPS and overall survival (OS) was observed [mGPS = 0: median 28.9 months, 95% confidence interval (CI) 25.9-33.6 months; mGPS = 1: median 21.4 months, 95% CI 17.6-26.1 months; mGPS = 2: median 16.8 months, 95% CI 14.3-21.2 months; P < 0.00001]. Similar results were found when comparing progression-free survival between groups. The effect of mGPS on survival did not depend on the applied treatment regimen (P = 0.21). In female patients, a trend towards longer OS was observed in Arm A versus Arm B, with this effect being clearly more pronounced in the mGPS cohort 0 (41.6 versus 25.5 months; P = 0.056). By contrast, median OS was longer in male patients with an mGPS of 1-2 treated in Arm B versus Arm A (20.8 versus 17.4 months; P = 0.022).

CONCLUSION

We demonstrate the role of mGPS as an independent predictor of OS regardless of the treatment regimen in mCRC patients receiving first-line treatment. mGPS may help identify gender-specific subgroups that benefit more or less from upfront intensive therapy.

Support Through Remote Observation and Nutrition Guidance (STRONG), a digital health intervention to reduce malnutrition among pancreatic cancer patients: A study protocol for a pilot randomized controlled trial

Background

Malnutrition is a common and distressing condition among pancreatic cancer patients. Fewer than a quarter of pancreatic cancer patients receive medical nutrition therapy (MNT), important for improving nutritional status, weight maintenance, quality of life and survival. System, provider, and patient level barriers limit access to MNT. We propose to examine the feasibility of a 12-week multi-level, digital health intervention designed to expand MNT access among pancreatic cancer patients.

Methods

Individuals with advanced pancreatic cancer starting chemotherapy (N = 80) will be 1:1 randomized to the intervention or usual care. The Support Through Remote Observation and Nutrition Guidance (STRONG) intervention includes system-level (e.g., routine malnutrition and screening), provider-level (e.g., dietitian training and web-based dashboard), and patient-level strategies (e.g., individualized nutrition plan, self-monitoring of dietary intake via Fitbit, ongoing goal monitoring and feedback). Individuals receiving usual care will be referred to dietitians based on their oncologists' discretion. Study assessments will be completed at baseline, 4-, 8-, 12-, and 16-weeks.

Results

Primary outcomes will be feasibility (e.g., recruitment, retention, assessment completion) and acceptability. We will collect additional implementation outcomes, such as intervention adherence, perceived usability, and feedback on intervention quality via an exit interview. We will collect preliminary data on outcomes that may be associated with the intervention including malnutrition, quality of life, treatment outcomes, and survival.

Conclusion

This study will advance our knowledge on the feasibility of a digital health intervention to reduce malnutrition among individuals with advanced pancreatic cancer. Trial registration: NCT05675059, registered on December 9, 2022.

Prognostic significance of the immuno-peritoneal cancer index in peritoneal metastatic patients treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

PURPOSE

A valid comparison of immune function among different patients with different primary pathologies or even with different tumour burdens requires the common use of a reliable assessment of the patient's condition. The combined immuno-PCI system can translate a complex clinical situation into a simple point value to improve postoperative outcomes to assess the prognostic significance of combined immuno-PCI in peritoneal metastatic patients treated with cytoreductive surgery(CRS) and hyperthermic intraperitoneal chemotherapy(HIPEC).

PATIENTS AND METHODS

Four hundred twenty-four patients from the prospectively maintained database of Dokuz Eylul University Peritoneal Surface Malignancy Center were retrospectively analysed. In addition to the demographic findings and the well-known clinicopathologic factors, several systemic inflammation-based prognostic scores, including the modified Glasgow prognostic score (mGPS), CRP-albumin ratio (CAR), neutrophil-lymphocyte ratio (NLR), neutrophil-thrombocyte ratio (NTR), and thrombocyte count, were all searched and stratified into scoring categories as prognostic determinants of surgical complications, final oncologic outcomes, recurrent disease, disease-free survival (DFS), and overall survival (OS). ROC analyses were performed, and cut-off values were obtained for all immune parameters by using the Youden index method.

RESULTS

There were 314 (74%) women and 110 (26%) men. The median age was 56 (ranging from 18 to 86) years. The most frequent sites of peritoneal metastasis were colorectal (n = 204; 48%) and gynaecologic carcinomas (n = 187; 44%). Thirty-three patients (8%) had primary malignant peritoneal mesothelioma. The median follow-up was 37.8 (ranging from 1 to 124) months. The overall survival was 51.7%. The 1-year, 3-year, and 5-year survival rates were estimated as 80%, 48.4%, and 32.6%, respectively. PCI-CAR-NTR (1 to 3) (p < .001) scoring was an independent prognostic factor for DFS. In a Cox backwards regression analysis, anastomotic leak (p = .002), completeness of cytoreduction (p = .0014), number of organ resections (p = .002), lymph node involvement (p = .003), and PCI-CAR-NTR (1 to 3) scoring (p = .001) were found to be independently significant prognostic factors for overall survival.

CONCLUSION

The PCI is a reliable and consistently valid prognostic factor to evaluate the tumour burden and tumour extent in patients treated with CRS/HIPEC. Staging the host by combining the PCI with an immunoscore may help to improve the outcomes of complications and overall survival in these complex cancer patients. The aggregate maximum immuno-PCI tool may be a better prognostic measure for outcome evaluation.

Multimodal survival prediction in advanced pancreatic cancer using machine learning

Background

Existing risk scores appear insufficient to assess the individual survival risk of patients with advanced pancreatic ductal adenocarcinoma (PDAC) and do not take advantage of the variety of parameters that are collected during clinical care.

Methods

In this retrospective study, we built a random survival forest model from clinical data of 203 patients with advanced PDAC. The parameters were assessed before initiation of systemic treatment and included age, CA19-9, C-reactive protein, metastatic status, neutrophil-to-lymphocyte ratio and total serum protein level. Separate models including imaging and molecular parameters were built for subgroups.

Results

Over the entire cohort, a model based on clinical parameters achieved a c-index of 0.71. Our approach outperformed the American Joint Committee on Cancer (AJCC) staging system and the modified Glasgow Prognostic Score (mGPS) in the identification of high- and low-risk subgroups. Inclusion of the KRAS p.G12D mutational status could further improve the prediction, whereas radiomics data of the primary tumor only showed little benefit. In an external validation cohort of PDAC patients with liver metastases, our model achieved a c-index of 0.67 (mGPS: 0.59).

Conclusions

The combination of multimodal data and machine-learning algorithms holds potential for personalized prognostication in advanced PDAC already at diagnosis.

•

We developed a machine-learning-based prediction model that outperforms the AJCC staging system and mGPS.

•

Applying our model to an external validation cohort demonstrates generalizability.

•

Explainable machine learning enables to understand the decision making of our model and identifies relevant parameters.

•

Combining clinical, imaging and genetic data holds potential for personalized prognostication in advanced PDAC.

The application of the Glasgow prognostic score to predict the survival in patients with metastatic pancreatic carcinoma

Objectives:

Thither is a more pressing effort to think about chemotherapy (CTx) in second-line and beyond in patients with metastatic pancreatic cancer (mPC). The current work aimed to evaluate the value of the Glasgow prognostic score (GPS) and modified Glasgow prognostic score (mGPS) to predict the survival in patients receiving second-line CTx protocol.

Material and Methods:

We retrospectively reviewed the patients’ medical files with mPC who received second-line CTx protocol between September 2013 and December 2017. The GPS/mGPS graded from 0 to 2 based on C-reactive protein and serum albumin.

Results:

One hundred and sixty-nine patients with mPC were eligible. Survival of patients with Score 0 (GPS/mGPS) was better than that of Score 1 (GPS/mGPS) or Score 2 (GPS/mGPS), which was statistically significant (P < 0.001). Of 78 patients who died, only 16 patients belonged to Score 0 (GPS/mGPS), compared to 30 patients belonged to Score 1 (GPS/mGPS) and 32 patients belonged to Score 2 (GPS/mGPS). Univariate analysis showed that high GPS/mGPS (P < 0.000) as well as poor Eastern Cooperative Oncology Group Performance Status (P < 0.000) and metastasis either to the liver (P < 0.01) or lung (P < 0.04) were linked with worse prognosis. A statistically significant association was detected between the two scores. Cohen’s Kappa coefficient (k) was 0.9, SD = 0.03; 95% CI (0.787–0.922; P < 0.001).

Conclusion:

Our data suggested that GPS/mGPS is an easy and applicable index that may be used in daily practice and may help in the prognostic stratification of mPC patients to avert overtreatment in frail patients and raise the best supportive treatment concept.

Chemoradiotherapy for Locally Advanced Esophageal Squamous Cell Carcinoma

PURPOSE

Few studies have reported the impact of chemoradiotherapy (CRT) on the objective response of patients with locally advanced unresectable esophageal squamous cell carcinoma (ESCC). We evaluated the factors predicting therapeutic effectiveness and the short- and long-term outcomes in patients with T4b ESCC treated with CRT.

METHODS

We included 155 patients with T4b ESCC who underwent CRT at the Department of Surgery, Gastroenterological Center, Yokohama City University, between January 2000 and December 2018. Responders were defined as patients who demonstrated a complete response (CR) or partial response (PR). Multivariate analysis for objective response was performed using a logistic regression model, and prognostic factors were evaluated by univariate and multivariate analyses.

RESULTS

Among the 155 patients included, 20 and 84 patients demonstrated a CR and PR, respectively, resulting in a response rate of 67.1%. The median overall survival (OS) was 15.2 months, and the 3-year survival rate was 32.1%. High Glasgow prognostic score (GPS) and advanced N-category independently predicted the objective response to CRT. GPS and objective response were independent prognostic factors for OS. There was no significant difference in the long-term survival of responders who received subsequent chemotherapy or salvage surgery.

CONCLUSIONS

High GPS and advanced N-category predicted a poor objective response to CRT in patients with T4b ESCC. Therefore, chemotherapeutic regimens with a higher efficacy are required. The indications for salvage surgery for responders should be carefully considered, with care taken to avoid complications. To confirm this, prospective randomized controlled studies are necessary.

Prediagnostic Inflammation and Pancreatic Cancer Survival

BACKGROUND

Chronic inflammation may promote initiation and progression of pancreatic cancer, but no studies have examined the association between inflammation in the period before diagnosis and pancreatic cancer survival.

METHODS

We prospectively examined the association of prediagnostic plasma levels of C-reactive protein, interleukin-6, and tumor necrosis factor-α receptor 2 with survival among 492 participants from 5 large US prospective cohort studies who developed pancreatic cancer. Using an empirical dietary inflammatory pattern (EDIP) score, we evaluated whether long-term proinflammatory diets were associated with survival among 1153 patients from 2 of the 5 cohorts. Cox proportional hazards regression was used to estimate hazard ratios for death with adjustment for potential confounders. All statistical tests were 2-sided.

RESULTS

Higher prediagnostic levels of C-reactive protein, interleukin-6, and tumor necrosis factor-α receptor 2 were individually associated with reduced survival (Ptrend = .03, .01, and .04, respectively). Compared with patients with a combined inflammatory biomarker score of 0 (all 3 marker levels below medians), those with a score of 3 (all 3 marker levels above medians) had a hazard ratio for death of 1.57 (95% confidence interval = 1.16 to 2.12; Ptrend = .003), corresponding to median overall survival times of 8 vs 5 months. Patients consuming the most proinflammatory diets (EDIP quartile 4) in the prediagnostic period had a hazard ratio for death of 1.34 (95% confidence interval = 1.13 to 1.59; Ptrend = .01), compared with those consuming the least proinflammatory diets (EDIP quartile 1).

CONCLUSION

Prediagnostic levels of inflammatory biomarkers and long-term proinflammatory diets were inversely associated with pancreatic cancer survival.

Significance of the Glasgow prognostic score for short-term surgical outcomes: A nationwide survey using the Japanese National Clinical Database

AIM

Preoperative inflammation-based Glasgow prognostic score (GPS) is a useful tool for predicting long-term prognosis in cancer patients. However, its association with postoperative short-term outcomes remains unknown. The aim of this study is to investigate the association between GPS and postoperative morbidity and mortality among patients undergoing surgery for various gastrointestinal malignancies.

METHODS

Using the Japanese National Clinical Database, we analyzed the records of 312 357 patients with gastrointestinal malignancy who underwent six typical elective surgeries, including esophagectomy, distal gastrectomy, total gastrectomy, right hemicolectomy, low anterior resection, and pancreaticoduodenectomy, between January 2015 and December 2018. We assigned GPS of 0, 1, or 2 to patients with no, one, or both decreased albumin and elevated C-reactive protein levels, respectively. We investigated the relationship of GPS with operative morbidity and mortality for each procedure with adjustments for patients' demographics, preoperative status, comorbidities, and cancer stages.

RESULTS

Crude operative morbidity was significantly higher for GPS 1 and 2 than GPS 0 patients in all procedures except pancreaticoduodenectomy. The postoperative length of hospital stay was significantly longer for GPS 1 and 2 patients in all procedures (P < .001). Operative mortality was also higher for GPS 1 and 2 patients in all procedures. The associations remained significant after adjustments for potential confounders of age, sex, physical status, tumor classification, use of preoperative therapy, and comorbidities.

CONCLUSION

This nationwide study provides solid evidence on the strong association between GPS and postoperative outcomes.

Pancreatic ductal adenocarcinoma and distal cholangiocarcinoma: a proposal of preoperative diagnostic score for differential diagnosis

PURPOSE

The differential diagnosis between primary adenocarcinoma of the pancreas head and distal cholangiocarcinoma remains a clinical challenge. Recent studies have shown important differences in terms of survival between these tumors. Therefore, different treatments should be considered, but the preoperative histological diagnosis is still difficult. Aim of this study is to create a preoperative diagnostic score for differential diagnosis between primary pancreatic adenocarcinoma and primary distal cholangiocarcinoma.

METHODS

One hundred eighty consecutive patients who underwent pancreaticoduodenectomy at Sapienza University of Rome from January 2010 to December 2019 were retrospectively analyzed. Inclusion criteria were pancreatic or biliary histologic origin obtained by definitive postoperative histological examination. Exclusion criteria were diagnosis of ampullary carcinoma, non-ampullary duodenal adenocarcinoma, pancreatic metastasis, and benign disease. One hundred one patients were considered eligible for the retrospective study. Preoperative biological, clinical, and radiological parameters were considered.

RESULTS

CRP > 10 mg/dL (p = 0.001), modified Glasgow Prognostic Score 2 (p = 0.002), albumin < 35 g/L (p = 0.05), CA 19-9 > 230 U/mL (p = 0.001), and Wirsung diameter > 3 mm (p < 0.001) were significant at univariate logistic analysis. Multivariate logistic analysis has shown that parameters independently associated with primary pancreatic adenocarcinoma were CRP > 10 mg/dL (p = 0.012), CA 19-9 > 230 U/mL (p = 0.043), and diameter of the Wirsung > 3 mm (p = 0.005). Through these parameters, a diagnostic score has been developed to predict a primary pancreatic adenocarcinoma when > 1 and a primary distal cholangiocarcinoma when < 1.

CONCLUSION

This feasible and low-cost diagnostic score could have a potential impact to differentiate pancreatic cancer histologic origin and to improve target therapeutic strategy.

A Prognostic Score for Predicting Survival in Patients With Pancreatic Head Adenocarcinoma and Distal Cholangiocarcinoma

BACKGROUND/AIM

Survival of patients with pancreatic cancer remains poor despite improvements in therapeutic strategies. This study aims to create a novel preoperative score to predict prognosis in patients with tumors of the pancreaticobiliary head.

PATIENTS AND METHODS

Data on 190 patients who underwent to pancreaticoduodenectomy at Sapienza University of Rome from January 2010 to December 2018 were retrospectively analyzed. After exclusion criteria, 101 patients were considered eligible for retrospective study. Preoperative biological, clinical and radiological parameters were considered.

RESULTS

Pancreatic ductal adenocarcinoma [hazard ratio (HR)=1.995, 95% confidence intervaI (CI)=1.1-3.3; p=0.01], carbohydrate antigen 19.9 (CA 19.9) >230 U/ml (HR=2.414, 95% CI=2.4-1.5, p<0.0001) and Wirsung duct diameter >3 mm (HR=1.592, 95% CI=1.5-0.9; p=0.08) were the only parameters associated with poor prognosis. Through these parameters, a prognostic score (PHT score) was developed which predicted worst survival when exceeding 2 and better survival when ≤2.

CONCLUSION

The PHT score may have a potential impact on predicting overall survival and consequently modulate the timing and type of treatment (up-front surgery vs. neoadjuvant therapy) patients are offered.

Chemotherapy-induced neutropenia as a prognostic factor in patients with pancreatic cancer treated with gemcitabine plus nab-paclitaxel: a retrospective cohort study

OBJECTIVES

Chemotherapy-induced neutropenia (CIN) is a common adverse event of chemotherapy. Several reports have suggested that CIN could be an important prognostic factor in chemotherapy of various cancers. However, whether CIN is a prognostic factor in unresectable pancreatic cancer (PC) treated with gemcitabine plus nab-paclitaxel (GnP) is unknown. The primary endpoint of this study was to compare overall survival (OS) between patients with severe CIN (grade ≥ 3) and those with absent/mild CIN (grade ≤ 2) in unresectable PC cases treated with GnP as first-line chemotherapy.

METHODS

A retrospective, cohort study was conducted using data from a computerized database. A total of 290 patients with pathologically confirmed PC treated with GnP as first-line chemotherapy were analyzed (severe CIN: ≥ grade 3, n = 174; absent/mild CIN: ≤ grade 2, n = 116).

RESULTS

The median OS was longer in the severe CIN group than in the absent/mild CIN group (19.2 months vs 11.3 months, respectively; P < 0.001). After adjustment, severe CIN was an independent predictive factor for OS (hazard ratio [HR], 0.53; 95% confidence interval [CI], 0.38-0.74; P < 0.001). After adjustment by time-varying covariates, severe CIN was still a significant prognostic factor for OS (HR, 0.79; 95% CI 0.69-0.91, P = 0.001).

CONCLUSION

The present results show that severe CIN is an independent and useful prognostic factor in PC patients treated with GnP.

Glasgow Prognostic Score (GPS) and Tumor Response as Biomarkers of Nivolumab Monotherapy in Third- or Later-line Setting for Advanced Gastric Cancer

BACKGROUND/AIM

This study aimed to seek clinical biomarkers of nivolumab monotherapy for advanced gastric cancer (AGC) of which efficacy is limited. We focused on Glasgow Prognostic Score (GPS), which reflects systemic inflammatory and nutritional status as well as disease control by chemotherapy immediately before nivolumab (DCBC).

PATIENTS AND METHODS

AGC patients with measurable lesions who were treated with nivolumab in the third- or later-line were included. DCBC was defined as a best overall response of complete response (CR), partial response, stable disease, or non-CR/non-progressive disease achieved by chemotherapy immediately before nivolumab.

RESULTS

Eighty patients were analyzed. Among the various clinical factors, multivariable analysis revealed that a GPS of 2 was significantly associated with a shorter overall survival and DCBC was significantly associated with a longer progression-free survival.

CONCLUSION

We present the potential of GPS and DCBC as efficient biomarkers of nivolumab for AGC, that warrants further evaluation.

Is Postoperative Adjuvant Transcatheter Arterial Infusion Therapy Effective for Patients with Hepatocellular Carcinoma who Underwent Hepatectomy? A Prospective Randomized Controlled Trial

BACKGROUND

The effectiveness of adjuvant transcatheter arterial chemo- or/and chemoembolization therapy after curative hepatectomy of initial hepatocellular carcinoma (HCC) is controversial. This study aimed to evaluate whether hepatectomy combined with adjuvant transcatheter arterial infusion therapy (TAI) for initial HCC has better long-term survival outcomes than hepatectomy alone.

METHODS

From January 2012 to December 2014, a prospective randomized controlled trial of patients with initial HCC was conducted. Then, 114 initial HCC patients were recruited to undergo hepatectomy with adjuvant TAI (TAI group, n = 55) or hepatectomy alone (control group, n = 59) at our institution. The TAI therapy was performed twice, at 3 and 6 months after curative hepatectomy (UMIN 000011900).

RESULTS

The patients treated with TAI had no serious side effects, and operative outcomes did not differ between the two groups. No significant differences were found in the pattern of intrahepatic recurrence or time until recurrence between the two groups. Moreover, no significant differences were found in the relapse-free survival or overall survival. Low cholinesterase level (< 200) had been identified as a risk factor affecting relapse-free survival. Furthermore, compared with surgery alone, adjuvant TAI with hepatectomy improved the overall survival for lower-cholinesterase patients.

CONCLUSIONS

Adjuvant TAI is safe and feasible, but it cannot reduce the incidence of postoperative recurrence or prolong survival for patients who underwent curative hepatectomy for initial HCC.

The prevalence of cancer associated systemic inflammation: Implications of prognostic studies using the Glasgow Prognostic Score

The prognostic importance of SIR in patients with cancer is widely recognised. More recently it has become clear that the systemic inflammatory response is an important etiologic factor in the development of cancer cachexia. Two recent meta-analysis carried out in 2017 and 2018 were interrogated and the number of patients with specific cancer types were identified. The percentage of patients with operable cancer (n>28,000) who were systemically inflamed varied from 21% to 38%. The percentage of patients with inoperable cancer (n>12,000) who were systemically inflamed varied from 29% to 79%. Overall, the percentage of patients (n>40,000) who were systemically inflamed varied from 28% to 63% according to tumour type. The most commonly studied cancer was colorectal cancer (n∼10,000 patients) and 40% were systemically inflamed.

A Multicenter Retrospective Study of Gemcitabine Plus Nab-Paclitaxel for Elderly Patients With Advanced Pancreatic Cancer

OBJECTIVES

This study aimed to assess the lesser known therapeutic benefit, particularly safety and effectiveness of gemcitabine plus nab-paclitaxel (GnP) treatment in elderly patients with advanced pancreatic cancer.

METHODS

We retrospectively enrolled advanced pancreatic cancer patients aged ≥75 years who received GnP as first-line treatment between December 2014 and December 2016. We assessed survival, adverse events, and early treatment discontinuation.

RESULTS

The cohort comprised 116 patients (median age, 77 [range, 75-84] years). The overall survival and progression-free survival were 21.8 and 12.1 months in patients with locally advanced cancer and 13.3 and 5.9 months, in patients with metastasis, respectively. The response and disease control rates were 31% and 81%, respectively. Within the first 2 months of treatment, grade 4 hematological and grade 3-4 nonhematological toxicities occurred in 10 and 23 patients, respectively. Early discontinuation due to adverse events occurred in 12 patients; the associated risk factors were age ≥80 years (odds ratio, 9.43) and serum albumin level <3.5 g/dL (odds ratio, 5.12).

CONCLUSIONS

In selected patients aged ≥75 years, GnP showed acceptable toxicities and effectiveness. However, patients aged ≥80 years and those with serum albumin levels <3.5 g/dL should be carefully assessed for treatment eligibility.

FOLFIRINOX in patients with peritoneal carcinomatosis from pancreatic adenocarcinoma: a retrospective study

Background

Peritoneal carcinomatosis (pcm) in metastatic pancreatic ductal adenocarcinomas (mpdac) is frequently encountered in day-to-day practice, but rarely addressed in the literature. The objective of the present study was to describe the management and outcome of patients diagnosed with pcm.

Methods

Data for all consecutive patients with mpdac treated in our centre between 1 January 2014 and 31 August 2015 were analyzed retrospectively. Computed tomography imaging was centrally reviewed by a dedicated radiologist to determine the date of pcm diagnosis.

Results

The analysis included 48 patients. Median age in the group was 61 years, and 41 patients had an Eastern Cooperative Oncology Group performance status (ecog ps) of 0-1. All patients presented with pcm either synchronously (group 1) or metachronously (group 2). Those groups differed significantly by baseline ecog ps and neutrophil-to-lymphocyte ratio (nlr), with ecog ps being poorer and nlr being higher in group 1. In addition to pcm, the main sites of metastasis were liver (62.5%) and lungs (31.3%). First-line chemotherapy in 36 patients (75%) was folfirinox (fluorouracil-irinotecan-leucovorin-oxaliplatin). The median overall survival for the entire population was 10.81 months [95% confidence interval (ci): 7.16 months to 14.16 months]; it was 13.17 months (95% ci: 5.9 months to 15.4 months) for patients treated with folfirinox. Median overall survival was 7.13 months (95% ci: 4.24 months to 10.41 months) for patients in group 1 and 14.34 months (95% ci: 9.79 months to 19.91 months) for patients in group 2, p = 0.1296.

Conclusions

Compared with other metastatic sites, synchronous pcm seems to be a poor prognostic factor. It could be more frequently associated with a poor ecog ps and a nlr greater than 5 in this group of patients. In patients with mpdac and pcm, either synchronous or metachronous, folfirinox remains an efficient regimen.

Pancreas Cancer-Associated Weight Loss

Unintentional weight loss in patients with pancreatic cancer is highly prevalent and contributes to low therapeutic tolerance, reduced quality of life, and overall mortality. Weight loss in pancreatic cancer can be due to anorexia, malabsorption, and/or cachexia. Proper supportive care can stabilize or reverse weight loss in patients and improve outcomes. We review the literature on supportive care relevant to pancreatic cancer patients, and offer evidence-based recommendations that include expert nutritional assessment, counseling, supportive measures to ensure adequate caloric intake, pancreatic enzyme supplementation, nutritional supplement replacement, orexigenic agents, and exercise. Pancreatic Cancer Action Network-supported initiatives will spearhead the dissemination and adoption of these best supportive care practices. IMPLICATIONS FOR PRACTICE: Weight loss in pancreatic cancer patients is endemic, as 85% of pancreatic cancer patients meet the classic definition of cancer cachexia. Despite its significant prevalence and associated morbidity, there is no established approach to this disease entity. It is believed that this is due to an important knowledge gap in understanding the underlying biology and lack of optimal treatment approaches. This article reviews the literature regarding pancreas cancer-associated weight loss and establishes a new framework from which to view this complex clinical problem. An improved approach and understanding will help educate clinicians, improve clinical care, and provide more clarity for future clinical investigation.

Prognostic significance of inflammation-based prognostic scoring in patients with upper urinary tract urothelial carcinoma

OBJECTIVES

To investigate whether Glasgow Prognostic Score has prognostic significance in patients with upper urinary urothelial carcinoma.

PATIENTS AND METHODS

We retrospectively reviewed the clinical records of 74 patients with upper urinary urothelial carcinoma. We set the cut-off value for C-reactive protein as 1.0mg/dL, and 3.5mg/dL for albumin as Glasgow Prognostic Score. Their blood data including albumin and C-reactive protein for Glasgow Prognostic Score and cytokeratin 19 fragment 21-1 as a tumor marker were measured before starting treatment. The patients were stratified into three groups with Glasgow Prognostic Score: The Group-1, albumin ≥3.5g/dL and C-reactive protein < 1.0mg/dL; Group-2, albumin < 3.5g/dL or C-reactive protein ≥1.0mg/dL; Group-3, albumin < 3.5g/dL and C-reactive protein ≥1.0mg/dL.

RESULTS

The median follow-up for all patients was 26.9 months (range: 10.9-91.1 months), during which 37 (50%) patients died. There was a signifi cant difference in the estimated survival rate among the 3 groups stratified by Glasgow Prognostic Score. The estimated survival rate in the Group-1 was significantly higher than those in Groups 2 and 3. In the univariate analysis C-reactive protein, serum cytokeratin 19 fragment 21-1 and Glasgow Prognostic Score were significant predictors of overall survival. On the multivariate analysis, serum cytokeratin 19 fragment 21-1 and Glasgow Prognostic Score were independently associated with shorter overall survival.

CONCLUSION

Our review suggests Glasgow Prognostic Score may play as a prognostic predictor for upper urinary urothelial carcinoma.

Prognostic importance of the preoperative modified systemic inflammation score for patients with gastric cancer

BACKGROUND

The systemic inflammation score (SIS), based on preoperative serum albumin (Alb) level and lymphocyte-to-monocyte ratio (LMR), has been shown to be a novel prognostic score for some tumors. We investigate the prognostic value of the SIS in patients with resectable gastric cancer (GC).

METHODS

Patients with GC who underwent curative resection between December 2008 and December 2013 were included. Time-dependent receiver operating characteristics analysis (t-ROC), concordance index (C-index) and AUC were used to compare the prognostic impact.

RESULTS

Totally, 1786 patients with resectable GC were included in the study. By multivariate analysis, the SIS was not an independent prognostic factor. However, the normal Alb level (≥ 40 g/l) and LMR ≥ 3.4 both remained independent protective factors for GC (both P < 0.05). Due to the similar survival of patients with LMR ≥ 3.4 and LMR < 3.4 in the normal Alb group, we combined the two subgroups to establish the modified SIS (mSIS). Multivariate analysis revealed that the mSIS was the only significant independent biomarker (P < 0.05). The t-ROC curve and C-index for the mSIS were superior to those of the SIS throughout the observation period. Furthermore, the AUC of the mSIS was significantly greater than that of the SIS at 3 and 5 years after operation (both P < 0.05).

CONCLUSION

The preoperative mSIS is a novel, simple and useful prognostic factor for postoperative survival in patients with GC and can be used as a part of the preoperative risk stratification process to improve the prediction of clinical outcomes.

The Comparison of Inflammation-Based Prognostic Scores in Patients With Extrahepatic Bile Duct Cancer After Pancreaticoduodenectomy

BACKGROUND

Inflammation-based prognostic scores are associated with tumor recurrence and survival in various cancers. The aim of this study was to identify the significance of inflammation-based prognostic scores and to detect the most useful score in patients with distal extrahepatic bile duct cancer after pancreaticoduodenectomy.

METHODS

Between 2000 and 2015, 121 patients were enrolled in this retrospective study. The relationship between clinicopathological variables including various prognostic scores and disease-free (DFS) as well as overall (OS) survival was investigated by univariate analysis. The area under the receiver operating characteristics curve was calculated to compare the predictive ability of each scoring system. Multivariate analysis was performed to identify the clinicopathological variables associated.

RESULTS

In univariate analysis, Glasgow prognostic score (GPS), mGPS, C-reactive protein/Alb ratio score, prognostic index, and preoperative monocyte count were significant risk factors for both DFS and OS. The area under the receiver operating characteristics curve of GPS is consistently larger in comparison with other four scores in both DFS as well as OS. In multivariate analysis, GPS was an independent risk factor of both tumor recurrence and poor prognosis.

CONCLUSIONS

GPS score is an independent tumor recurrence and prognostic factor in patients with distal extrahepatic bile duct cancer and is superior to the other prognostic scores.

Inflammation-Based Prognostic Score Predicts Postoperative Survival of Patients with Interstitial Pneumonia After Undergoing Lung Cancer Resection

OBJECTIVES

Idiopathic interstitial pneumonias (IIPs) are associated with an increased risk of lung cancer. Glasgow prognostic score (GPS), which uses serum C-reactive protein (CRP) and albumin levels to indicate systemic inflammatory response and nutrition level, has been reported to be a predictor of overall survival in patients with various types of cancer. We evaluated the usefulness of GPS for prediction of survival of patients with both lung cancer and IIPs following a lung resection procedure.

METHODS

Patients with IIPs who underwent lung cancer resection from January 2006 through December 2015 were investigated. Routine laboratory measurements, including serum CRP and albumin for determining GPS, were performed before the operation. Univariate and multivariate analyses with a COX proportional hazards regression model were used to identify independent risk factors for overall survival (OS), relapse-free survival (RFS), cancer-specific survival (CSS), and other disease-specific survival (ODSS).

RESULTS

A total of 135 patients underwent lung resection during the study period. Multivariate analysis selected sublobar resection (p = 0.035), UIP pattern (p = 0.025), and GPS of 1-2 (p = 0.042) as predictive factors associated with OS, while GPS of 1-2 (p = 0.039) was shown to be a predictive factor associated with RFS. Multivariate analysis also revealed pTNM (p < 0.001), usual interstitial pneumonia pattern (p = 0.006), and GPS of 2 (p = 0.003) as predictive factors associated with CSS, while univariate analysis indicated pTNM (p = 0.042), GPS of 1 (p = 0.044), and %DLCO (p = 0.038) as predictive factors associated with ODSS.

CONCLUSION

GPS is an independent prognostic factor of OS and RFS in lung cancer patients with IIPs undergoing a lung resection procedure. Furthermore, a GPS of 2 was found to be associated with CSS following lung cancer resection, while a score of 1 was associated with ODSS.

NARCA: A novel prognostic scoring system using neutrophil-albumin ratio and Ca19-9 to predict overall survival in palliative pancreatic cancer

BACKGROUND AND OBJECTIVES

Several serum based-markers and ratios have been investigated for their prognostic value in pancreatic ductal adenocarcinoma (PDAC). This cohort study aimed to combine these into a novel prognostic scoring system.

METHODS

A retrospective cohort study was performed on 145 patients with unresectable histologically-confirmed PDAC. Based on the existing literature the following markers were investigated: neutrophil-lymphocyte ratio (NLR), neutrophil-albumin ratio (NAR), platelet-lymphocyte ratio (PLR), fibrinogen, and Ca19-9. These values were dichotomized about their medians for Kaplan-Meier and Cox regression analysis.

RESULTS

Univariate Cox regression revealed statistically significant prognostic value for: NLR, NAR, PLR, fibrinogen, and Ca19-9. When combining these using Cox regression analysis adjusting for other prognostic indicators, only NAR (hazard ratios [HR] = 3.174, P = 0.022) and Ca19-9 (HR = 2.697, P = 0.031) were independent predictors of survival. Combining NAR and Ca19-9 we split the cohort into three "NARCA" groups: NARCA0 = NAR ≤ 0.13 and Ca19-9 ≤ 770, NARCA1 = either NAR > 0.13 or Ca19-9 >770, NARCA2 = NAR > 0.13 and Ca19-9 > 770. Median survival was 20.5, 9.7 and 4.1 months in NARCA0, 1, and 2 respectively ( P < 0.0005, log-rank test). A separate validation cohort confirmed the prognostic significance of the score ( P = 0.048).

CONCLUSIONS

Combining NAR and Ca19-9 into a prognostic score allows stratification of unresectable PDAC patients into groups with significantly different overall survival.

Evaluation of inflammation-based markers for predicting the prognosis of unresectable pancreatic ductal adenocarcinoma treated with chemotherapy

Predicting the prognosis of unresectable pancreatic ductal adenocarcinoma (PDAC) is useful in determining the appropriate management strategy. The present study aimed to investigate the association between PDAC prognosis and inflammation-based markers, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, prognostic nutritional index, modified Glasgow prognostic score (mGPS) and controlling nutritional status score. A total of 72 patients with unresectable PDAC who received chemotherapy were included. Inflammation-based markers were measured prior to treatment. The median progression-free survival (PFS) and overall survival (OS) were 117 days (range, 10-781 days) and 244 days (range 43-781 days), respectively. The cut-off value of continuous variables that predicted the median OS (244 days) was calcualted. Univariate analysis of PFS showed that disease stage, first-line chemotherapy regimen, carcinoembryonic antigen (CEA), NLR, platelet-to-lymphocyte ratio (PLR), mGPS and controlling nutritional status (CONUT) scores were associated with PFS. Among them, stage, first-line chemotherapy regimen, CEA, NLR and mGPS were independent prognostic factors for PFS in multivariate analysis. Univariate analysis of OS showed that stage, first-line chemotherapy regimen, CA19-9, NLR, PLR, prognostic nutritional index (PNI), mGPS and CONUT score were associated wtih OS. Among them, first-line chemotherapy and mGPS were independent prognostic factors for OS according to multivariate analysis. Univariate and multivariate analyses revealed that a NLR ≥4.0 and mGPS 2 were independent prognostic factors for PFS. For OS, mGPS 2 was an independent prognostic factor. In conclusion, mGPS was the most useful marker in predicting the prognosis of patients with unresectable PDAC who received chemotherapy.

Glasgow prognostic score is a practical predictive index for postoperative intra-abdominal septic complications after bowel resection in Crohn's disease patients

PURPOSE

Postoperative intra-abdominal septic complications (IASCs) are not uncommon in patients with Crohn's disease (CD). The appropriate index to predict postoperative IASCs in these individuals remains unknown. This study investigates whether the inflammation-based Glasgow prognostic score (GPS) is predictive in the setting of postoperative IASC CD patients who underwent elective bowel resection.

METHODS

A consecutive cohort of 163 CD patients who underwent elective intestinal resection from July 2012 to March 2016 was retrospectively analyzed. Patients were divided into two GPS groups, one lower and one higher. The GPS was defined by serum levels of C-reactive protein and albumin. Univariate and multivariate analyses were conducted to identify risk factors for postoperative IASCs.

RESULTS

Postoperative IASCs occurred in 25 (15.3%) patients. Compared with patients in the lower GPS group, patients with a higher GPS had a higher incidence of postoperative IASCs (9.85 vs. 38.71%, P < 0.001) and experienced longer postoperative hospital stay (10.53 ± 7.00 vs. 15.71 ± 9.17, P = 0.001). Univariate and multivariate analyses revealed preoperative GPS [odds ratio (OR) 5.016, 95% confidence interval (CI) 1.134-22.193, P = 0.034] and penetrating behavior (OR 4.495, 95% CI 1.377-14.670, P = 0.013) to be independent risk factors for postoperative IASCs.

CONCLUSIONS

A preoperative GPS can serve as a useful index for predicting manifestation of postoperative IASCs after bowel resection in patients with CD. Perioperative optimization is required to improve postoperative outcomes for patients with higher GPS.

Preoperative neutrophil-to-lymphocyte ratio and tumor-related factors to predict lymph node metastasis in patients with pancreatic ductal adenocarcinoma (PDAC)

As a poor prognosis indicator in patients with pancreatic ductal adenocarcinoma (PDCA), lymph node (LN) metastasis is of great importance in treatment. Present study was performed to evaluate the predictive value of preoperative neutrophil-to-lymphocyte ratio (NLR), Platelet-to-lymphocyte ratio (PLR) and possible clinical parameters on the LN metastasis in PDCA patients. A total of 159 operable patients with PDCA were enrolled in our study. The clinical utility of NLR and other clinical parameters was evaluated by receiver operating characteristic (ROC) curves. Overall survival analysis indicated that LN metastasis is an independent prognostic factor. The logistic analysis was used to determine the independent parameters associated with LN metastasis. Ideal cutoff values for predicting LN metastasis are 2.12 for NLR and 130.96 for PLR according to the ROC curve. Multivariate analyses indicate that NLR (HR 2.588; 95% CI 1.246-5.376; P = 0.011), CA125 (HR 6.348; 95% CI 2.056-19.594; P = 0.001) and CA19-9 (HR 2.738; 95% CI 1.151-6.515; P = 0.023) are associated significantly with LN metastasis independently. Preoperative NLR, CA125 and CA19-9 are useful biomarkers for the prediction of LN metastasis in PDCA patients.

High preoperative Glasgow prognostic score is a negative prognostic factor for patients with endometrial carcinoma

The aim of the present study was to determine the prognostic value of the Glasgow prognostic score (GPS) in endometrial carcinoma (EC). Patients with EC who underwent surgery at the Shimane University Hospital between January 1997 and December 2013 were enrolled (n=118). The associations between pretreatment GPS and clinical parameters, including age, histological type, International Federation of Gynecology and Obstetrics stage, tumor grade, carbohydrate antigen 19-9 and carcinoembryonic antigen levels, progression-free survival (PFS), and overall survival (OS), were investigated. Survival analysis was performed with the Kaplan-Meier method, and prognostic factors were evaluated with Cox's proportional hazards regression model. A high pretreatment GPS was associated with advanced clinical stage, histological type and tumor grade (P<0.001, P=0.007 and P=0.006, respectively). Multivariate analysis identified a high GPS as an independent negative prognostic factor for PFS and OS (P=0.025 and P=0.044, respectively). Therefore, a high pretreatment GPS has prognostic value and the potential to be a predictive marker for surgical outcome in patients with EC. Evaluation of pretreatment GPS may aid in the identification of high-risk populations, which may improve treatment selection and patient outcomes.

Esophageal stenosis and the Glasgow Prognostic Score as independent factors of poor prognosis for patients with locally advanced unresectable esophageal cancer treated with chemoradiotherapy (exploratory analysis of JCOG0303)

BACKGROUND

The aim of this study was to investigate the possible prognostic factors and predictive accuracy of the Glasgow Prognostic Score (GPS) for patients with unresectable locally advanced esophageal squamous cell carcinoma (LAESCC) treated with chemoradiotherapy.

METHODS

One hundred forty-two patients were enrolled in JCOG0303 and assigned to the standard cisplatin and 5-fluorouracil (PF)-radiotherapy (RT) group or the low-dose PF-RT group. One hundred thirty-one patients with sufficient data were included in this analysis. A Cox regression model was used to analyze the prognostic factors of patients with unresectable LAESCC treated with PF-RT. The GPS was classified based on the baseline C-reactive protein (CRP) and serum albumin levels. Patients with CRP ≤1.0 mg/dL and albumin ≥3.5 g/dL were classified as GPS0. If only CRP was increased or only albumin was decreased, the patients were classified as GPS1, and the patients with CRP >1.0 mg/dL and albumin <3.5 g/dL were classified as GPS2.

RESULTS

The patients' backgrounds were as follows: median age (range), 62 (37-75); male/female, 119/12; ECOG PS 0/1/2, 64/65/2; and clinical stage (UICC 5th) IIB/III/IVA/IVB, 3/75/22/31. Multivariable analyses indicated only esophageal stenosis as a common factor for poor prognosis. In addition, overall survival tended to decrease according to the GPS subgroups (median survival time (months): GPS0/GPS1/GPS2 16.1/14.9/8.7).

CONCLUSIONS

Esophageal stenosis was identified as a candidate stratification factor for randomized trials of unresectable LAESCC patients. Furthermore, GPS represents a prognostic factor for LAESCC patients treated with chemoradiotherapy.

Hamburg-Glasgow classification: preoperative staging by combination of disseminated tumour load and systemic inflammation in oesophageal carcinoma

Background:

The aim of this study was to establish a new preoperative staging classification and evaluate its comparability to the post-operative tumour stage, lymph node invasion and metastasis (TNM) classification. To date, adequate, preoperative staging in patients with oesophageal carcinoma (EC) is still missing but urgently needed. Systemic inflammation and disseminated tumour load have a pivotal role in recurrence and oncological outcome. To improve the clinical staging, we merged the Glasgow Prognostic Score (GPS) and disseminated tumour cells (DTC) into a new sufficient preoperative staging classification, the Hamburg-Glasgow classification (HGC).

Methods:

In this prospective, single-centre study, 326 patients following curative oesophagectomy were included. From all patients preoperative bone marrow was aspirated from the iliac crest to detect DTCs by immunostaining with the pan-keratin antibody A45-B/B3. HGC was subdefined into four prognostic groups on the basis of C-reactive protein (CRP), albumin and DTC. The three prognostic groups of the GPS were supplemented by DTC detection status. Results were correlated with clinicopathological parameters and clinical outcome.

Results:

Increasing HGC significantly correlated with lymph node invasion (P=0.022), post-operative pathohistological TNM staging (P=0.001) and tumour recurrence (P=0.001). The four HGC prognostic groups displayed a gradual decrease in overall as well as disease-free survival (P<0.001, each). Hamburg-Glasgow classification was a strong, significant independent predictor of overall survival and disease-free survival (P<0.001, both) in multivariate analysis.

Conclusions:

Hamburg-Glasgow classification seems to be a promising preoperative additive staging classification for accurate and simple outcome stratification.

Biliary drainage improves the predictive value of modified Glasgow Prognostic Scores in inoperable pancreatic cancer

Objective

To assess the influence of biliary drainage to cholangitis on modified Glasgow Prognostic Score (mGPS) in patients with pancreatic cancer.

Methods

mGPS was calculated before and after biliary drainage in 47 consecutive patients with inoperable pancreatic cancer who were receiving chemotherapy. Biliary drainage was indicated for malignant obstructive jaundice that prevented the administration of chemotherapy. To elucidate mGPS values, serum levels of CRP and albumin were measured at the time of diagnosis (before biliary drainage). Overall survival was evaluated and risk factors, which contribute to overall survival, were examined.

Results

Biliary drainage was performed in 15 patients. Using values obtained before biliary drainage, there were no significant differences in median survival time between patients with a mGPS of 0 and those with a mGPS of 1 or 2 (10.7 vs. 9.4 months; p = 0.757). However, using values obtained after biliary drainage, median survival time was significantly higher in patients with a mGPS of 0 than in those with a mGPS of 1 or 2 (11.4 vs. 4.7 months; p = 0.002). Multivariate analysis revealed that a mGPS of 1 or 2 (HR: 3.38; 95% CI: 1.35–8.46, p = 0.009), a carbohydrate antigen 19–9 >1000 U/mL (2.52; 1.22–5.23, p = 0.013), a performance status of 2 (7.68; 2.72–21.28, p = 0.001), carcinoembryonic antigen level >10 ng/mL (2.29; 1.13–4.61, p = 0.021) were independently associated with overall survival.

Conclusion

mGPS values obtained after biliary drainage appear to be a more reliable indicator of overall survival in patients with inoperable pancreatic cancer.

Prognostic Tools in Patients With Advanced Cancer: A Systematic Review

PURPOSE

In 2005, the European Association for Palliative Care made recommendations for prognostic markers in advanced cancer. Since then, prognostic tools have been developed, evolved, and validated. The aim of this systematic review was to examine the progress in the development and validation of prognostic tools.

METHODS

Medline, Embase Classic and Embase were searched. Eligible studies met the following criteria: patients with incurable cancer, >18 years, original studies, population n ≥100, and published after 2003. Descriptive and quantitative statistical analyses were performed.

RESULTS

Forty-nine studies were eligible, assessing seven prognostic tools across different care settings, primary cancer types, and statistically assessed survival prediction. The Palliative Performance Scale was the most studied (n = 21,082), comprising six parameters (six subjective), was externally validated, and predicted survival. The Palliative Prognostic Score composed of six parameters (four subjective and two objective), the Palliative Prognostic Index composed of nine parameters (nine subjective), and the Glasgow Prognostic Score composed of two parameters (two objective) and were all externally validated in more than 2000 patients with advanced cancer and predicted survival.

CONCLUSION

Various prognostic tools have been validated but vary in their complexity, subjectivity, and therefore clinical utility. The Glasgow Prognostic Score would seem the most favorable as it uses only two parameters (both objective) and has prognostic value complementary to the gold standard measure, which is performance status. Further studies comparing all proved prognostic markers in a single cohort of patients with advanced cancer are needed to determine the optimal prognostic tool.

Use of gemcitabine as a second-line treatment following chemotherapy with folfirinox for metastatic pancreatic adenocarcinoma

There is a lack of prospective data about second-line treatments for metastatic pancreatic ductal adenocarcinoma patients. This is partially due to recent changes in first-line chemotherapy treatments. Despite this dearth of information, 50.0% of the patients who experience failure with first-line folinic acid, 5-fluorouracil, irinotecan and oxaliplatin (folfirinox) treatment are eligible for additional chemotherapy. In this setting, gemcitabine is widely used without any standard recommendations available. The present study evaluated 42 patients who received gemcitabine subsequent to a first-line treatment of folfirinox between January 2008 and December 2012 at the Centre Léon Bérard (Lyon, France). Clinical data, biological data and tumor characteristics were retrospectively analyzed to identify prognostic factors for successful treatment with gemcitabine. In total, 11 patients (26.2%) experienced control of their cancer with gemcitabine treatment. However, there was no predictive marker for their response to the drug. The median overall survival was 3.6 months from gemcitabine initiation [95% confidence interval (CI), 2.1-5.1]. The median length of gemcitabine treatment was 1.5 months (95% CI, 0.3-13.3). Among the 11 patients who were successfully treated with gemcitabine, 6 were resistant to first-line folfirinox treatment. Patients who were non responsive to folfirinox had a higher probability of success with gemcitabine compared with patients that responded to folfirinox (54.5 vs. 21.4%, respectively; P=0.061). The present study did not identify any clinical or biological marker with a predictive value for successful gemcitabine treatment. Furthermore, successful gemcitabine treatment was not correlated with patients' response to first-line folfirinox treatment. This suggests an absence of cross-resistance in the chemotherapy protocols and provides evidence for effective cancer treatment with the second-line gemcitabine therapy.

The Role of Pancreatic Enzyme Replacement Therapy in Unresectable Pancreatic Cancer: A Prospective Cohort Study

OBJECTIVES

Although patients with pancreatic cancer (PC) are prone to exocrine pancreatic insufficiency, there are little evidence about pancreatic enzyme replacement therapy (PERT) in patients with PC, especially those receiving chemotherapy.

METHODS

This is a prospective consecutive observational study of PERT in patients with unresectable PC. We prospectively enrolled patients receiving chemotherapy for unresectable PC from April 2012 to February 2014 and prescribed oral pancrelipase of 48,000 lipase units per meal (pancrelipase group). N-benzoyl-tryrosyl para-aminobenzoic acid test was performed at baseline. Patients receiving chemotherapy before April 2012 were retrospectively studied as a historical cohort. Data on the nutritional markers at baseline and 16 weeks were extracted, and serial changes, defined as the ratio of markers at 16 weeks/baseline, were compared between 2 groups.

RESULTS

A total of 91 patients (46 in the pancrelipase group and 45 in the historical cohort) were analyzed. N-benzoyl-tryrosyl para-aminobenzoic acid test was low in 94% of the pancrelipase group. Serial change in the pancrelipase group versus historical cohort was 1.01 versus 0.95 in body mass index (P < 0.001) and 1.03 versus 0.97 in serum albumin (P = 0.131).

CONCLUSIONS

The rate of exocrine pancreatic insufficiency in unresectable PC was high, and PERT can potentially improve the nutritional status during chemotherapy.

Glasgow Prognostic Score predicts prognosis of intrahepatic cholangiocarcinoma

High Glasgow Prognostic Score (GPS) has been associated with poor prognosis in patients with lung, ovarian, colorectal and renal cancer, as well as hepatocellular carcinoma. The aim of this study was to investigate the prognostic value of GPS in patients with intrahepatic cholangiocarcinoma (ICC) undergoing partial hepatectomy. A total of 72 patients with pathologically confirmed ICC were classified according to their GPS scores assigned based on the preoperative levels of C-reactive protein (CRP) and albumin. Their clinicopathological data were retrospectively assessed using univariate and multivariate analysis to determine their association with overall survival and recurrence. High GPS scores in ICC patients were associated with preoperative levels of CRP (P<0.001) and albumin (P<0.001), frequency of ascites accumulation (P=0.035), lymph node metastasis (P=0.002) and tumour size (P=0.005). On univariate analysis, preoperative levels of CRP (P<0.001), albumin (P=0.016) and carbohydrate antigen 19-9 (P=0.038), hepatitis B virus (HBV) positivity (P=0.009), occurrence of lymph node metastasis (P=0.001), Child-Pugh class B (P=0.013) and high tumour-node-metastasis (TNM) stage (P=0.002) were found to be associated with the 1- and 3-year overall survival. Multivariate analysis suggested that GPS score (HR=2.037, 95% CI: 1.092-3.799, P=0.025), TNM classification (HR=2.000, 95% CI: 1.188-3.367, P=0.009) and HBV positivity (HR=0.559 95% CI: 0.328-0.953, P=0.032) were independently associated with patient survival. High GPS scores also predicted ICC recurrence. In conclusion, our results demonstrated that GPS may serve as an independent marker of prognosis in patients with ICC following partial hepatectomy.

Evaluation of the Glasgow Prognostic Score in patients receiving chemoradiotherapy for stage III and IV esophageal cancer

High Glasgow Prognostic scores (GPSs) have been associated with poor outcomes in various tumors, but the values of GPS and modified GPS (mGPS) in patients with advanced esophageal cancer receiving chemoradiotherapy (CRT) has not yet been reported. We have evaluated these with respect to predicting responsiveness to CRT and long-term survival. Between January 2002 and December 2011, tumor responses in 142 esophageal cancer patients (131 men and 11 women) with stage III (A, B and C) and IV receiving CRT were assessed. We assessed the value of the GPS as a predictor of a response to definitive CRT and also as a prognostic indicator in patients with esophageal cancer receiving CRT. We found that independent predictors of CRT responsiveness were Eastern Cooperative Oncology Group (ECOG) performance status, GPS and cTNM stage. Independent prognostic factors were ECOG performance status and GPS for progression-free survival and ECOG performance status, GPS and cTNM stage IV for disease-specific survival. GPS may be a novel predictor of CRT responsiveness and a prognostic indicator for progression-free and disease-specific survival in patients with advanced esophageal cancer. However, a multicenter study as same regime with large number of patients will be needed to confirm these outcomes.

Association between pretreatment Glasgow prognostic score and gastric cancer survival and clinicopathological features: a meta-analysis

BACKGROUND

Glasgow prognostic score (GPS) is widely known as a systemic inflammatory-based marker. The relationship between pretreatment GPS and gastric cancer (GC) survival and clinicopathological features remains controversial. The aim of the study was to conduct a meta-analysis of published studies to evaluate the association between pretreatment GPS and survival and clinicopathological features in GC patients.

METHODS

We searched PubMed, Embase, MEDLINE, and BioMed databases for relevant studies. Combined analyses were used to assess the association between pretreatment GPS and overall survival, disease-free survival, and clinicopathological parameters by Stata Version 12.0.

RESULTS

A total of 14 studies were included in this meta-analysis, including 5,579 GC patients. The results indicated that pretreatment high GPS (HGPS) predicted poor overall survival (hazard ratio =1.51, 95% CI: 1.37-1.66, P<0.01) and disease-free survival (hazard ratio =1.45, 95% CI: 1.26-1.68, P<0.01) in GC patients. Pretreatment HGPS was also significantly associated with advanced tumor-node-metastasis stage (odds ratio [OR] =3.09, 95% CI: 2.11-4.53, P<0.01), lymph node metastasis (OR =4.60, 95% CI: 3.23-6.56, P<0.01), lymphatic invasion (OR =3.04, 95% CI: 2.00-4.62, P<0.01), and venous invasion (OR =3.56, 95% CI: 1.81-6.99, P<0.01).

CONCLUSION

Our meta-analysis indicated that pretreatment HGPS could be a predicative factor of poor survival outcome and clinicopathological features for GC patients.

Glasgow prognostic score is an independent marker for poor prognosis with all cases of epithelial ovarian cancer

Inflammatory markers are important prognostic factors in various cancers. This study investigated whether inflammatory markers of the Glasgow prognostic score (GPS) predicted progression‐free survival (PFS) and overall survival (OS) for patients with all cases of epithelial ovarian cancer (OC). Pretreatment GPS was examined for the correlations with PFS and OS in 216 patients in all stages of epithelial OC. Statistical analyses were performed using the Mann–Whitney U‐test. PFS and OS were analyzed using the Kaplan–Meier method. Cox's proportional hazard regression was used for univariate and multivariate analyses. For all patients, the median PFS was 35.1 months, and median OS was 46.7 months; follow‐up range was 1–162 months. Kaplan–Meier analysis revealed that patients with high GPS (GPS 2) at pretreatment had a shorter PFS and OS than did patients with lower GPS (GPS 0 + 1) in for early, advanced, and all‐stages of OC (PFS: P < 0.001 for early‐, advanced‐ and all‐stages; OS; P < 0.001 for early‐ and all‐stage, P = 0.015 for advanced‐stage). GPS (GPS 2) was also found to be an independent predictor of both recurrence (P = 0.002) and survival (P = 0.001) of all cases of epithelial OC by a multivariate analysis. GPS can serve as an indicator of poor prognosis in patients with all stages of epithelial OC, including early‐stage disease and regardless of histology.

Prognostic and predictive markers in pancreatic adenocarcinoma

Pancreatic ductal adenocarcinoma is characterized by a poor prognosis and a low median survival, despite improvements observed for many other solid tumours. Intensive research efforts have been undertaken during the last decades to discover new prognostic and treatment predictive biomarkers for pancreatic ductal adenocarcinoma. The mainstay of medical treatment for the disease has been the well-tolerated nucleoside analogue, gemcitabine. The only targeted agent currently used in pancreatic ductal adenocarcinoma patients is the epithelial growth factor receptor inhibitor erlotinib in combination with gemcitabine. Recently, treatment regimens such as a combination of fluorouracil-leucovorin-irinotecan-oxaliplatin (FOLFIRINOX) and the combination of nab-paclitaxel with gemcitabine have been introduced for metastatic pancreatic ductal adenocarcinoma. Although these treatment regimens significantly improve survival of patients, there are no good predictive biomarkers available that can be used to identify who would benefit most from them. Therefore, the search for predictive biomarkers that would facilitate personalization of chemotherapy is highly relevant.

Improved Pancreatic Adenocarcinoma Diagnosis in Jaundiced and Non-Jaundiced Pancreatic Adenocarcinoma Patients through the Combination of Routine Clinical Markers Associated to Pancreatic Adenocarcinoma Pathophysiology

BACKGROUND

There is still no reliable biomarker for the diagnosis of pancreatic adenocarcinoma. Carbohydrate antigen 19-9 (CA 19-9) is a tumor marker only recommended for pancreatic adenocarcinoma follow-up. One of the clinical problems lies in distinguishing between this cancer and other benign pancreatic diseases such as chronic pancreatitis. In this study we will assess the value of panels of serum molecules related to pancreatic cancer physiopathology to determine whether alone or in combination could help to discriminate between these two pathologies.

METHODS

CA 19-9, carcinoembryonic antigen (CEA), C-reactive protein, albumin, insulin growth factor-1 (IGF-1) and IGF binding protein-3 were measured using routine clinical analyzers in a cohort of 47 pancreatic adenocarcinoma, 20 chronic pancreatitis and 15 healthy controls.

RESULTS

The combination of CA 19-9, IGF-1 and albumin resulted in a combined area under the curve (AUC) of 0.959 with 93.6% sensitivity and 95% specificity, much higher than CA 19-9 alone. An algorithm was defined to classify the patients as chronic pancreatitis or pancreatic cancer with the above specificity and sensitivity. In an independent validation group of 20 pancreatic adenocarcinoma and 13 chronic pancreatitis patients, the combination of the four molecules classified correctly all pancreatic adenocarcinoma and 12 out of 13 chronic pancreatitis patients.

CONCLUSIONS

Although this panel of markers should be validated in larger cohorts, the high sensitivity and specificity values and the convenience to measure these parameters in clinical laboratories shows great promise for improving pancreatic adenocarcinoma diagnosis.

Patterns of care and outcomes of older versus younger patients with metastatic pancreatic cancer: A Fox Chase Cancer Center experience

BACKGROUND

Older patients with metastatic pancreatic cancer (mPC) are poorly represented in clinical trials. We compared patterns of care and outcomes of patients with mPC < and >65 yrs (Group 1 and Group 2, respectively) treated at Fox Chase Cancer Center (FCCC) to identify predictors of survival and better understand the treatment approaches.

METHODS

Charts of 579 patients with mPC treated at FCCC from 2000 to 2010 were reviewed. Group 1 and Group 2 were compared with respect to baseline, treatment characteristics, and overall survival (OS) after diagnosis of metastatic disease.

RESULTS

299 patients in Group 1 (median age 57) and 280 patients in Group 2 (median age 73) were evaluated. Patients in Group 2 were less likely to receive any chemotherapy for mPC compared to Group 1 (65% vs 75%, p=0.001) and if treated were less likely to receive more than one agent (37% vs 53%, p<0.001). Survival was comparable between the two groups (p=0.16) and Charlson Co-morbidity Index did not emerge as a prognostic factor. Longer OS was associated with higher number of agents used in both groups (p<0.001). Liver metastases conferred worse survival (p=0.02) while lung metastases conferred better survival in both groups (p=0.002).

CONCLUSIONS

Older mPC patients are less likely to receive chemotherapy and receive fewer agents yet have similar OS compared to younger patients. OS improves with increasing number of agents, supporting the use of combination chemotherapy in healthy older patients. Our findings encourage enrollment of older patients with mPC with good performance status onto clinical trials with stratification by site of metastases.

Prognostication by inflammation-based score in patients with locally advanced pancreatic cancer treated with chemoradiotherapy

BACKGROUND

An association between inflammatory/immunonutritional status and patient prognosis has been reported in various types of cancer. The aim of this study was to evaluate the utility of inflammatory/immunonutritional factors as therapeutic predictors for patients with locally advanced pancreatic cancer treated with chemoradiotherapy (CRT).

METHODS

Ninety-six patients with histologically proven locally advanced pancreatic adenocarcinoma who underwent CRT were enrolled in this study. We evaluated significance of inflammation-based factors as predictors of therapeutic effect and prognosis.

RESULTS

The median progression free survival (PFS) and overall survival (OS) of all patients was 10 and 18 months, respectively. A Glasgow prognostic score (GPS) of 2 and plasma fibrinogen levels ≥ 400 mg/dL were independent predictors of poor PFS and OS. A prognostic nutritional index (PNI) ≥ 45 was a predictor of a significantly better reduction rate of the primary tumor. The prognosis between patients with GPS 0/1 and fibrinogen <400 mg/dL, GPS 2 or fibrinogen ≥400 mg/dL, and GPS 2 and fibrinogen ≥400 mg/dL were significantly different. Patients with GPS 2 and/or plasma fibrinogen ≥ 400 mg/dL had significantly higher incidence of metastasis within 6 months after CRT.

CONCLUSIONS

GPS, fibrinogen, PNI are useful therapeutic and prognostic predictors in patients with locally advanced pancreatic cancer treated with CRT.
